Hello, I have bought an Arduino Uno R4 wifi. But it just isn't getting recognized by my computer. I have been told that is is "a driver problem" so when i searched on the internet i installed way too many namely CHP340. Yet it still isn't getting recognized. The main problem i that it turns on the blink program that is in there by default is working, its just that when i plug it in it isn't getting seen at all not even a glimpse. I have already tried switching cables(both of them could send data i had tested them with my phone) , computers and even bought a new board and the problem still persits. I even tried on the arduino cloud. I also tried activating its wifi mode by clicking the reset button twice. (this is what Chatgpt told me) I did this to try programming it wirelessly but still no dice. my windows operting sytem is a Windows 11 i also tried it wih windows 10 pro and chrome OS. ---

Your topic does not indicate a problem with with the cloud en therefore has been moved to a more suitable location on the forum. > [@shloky1](#): > > its just that when i plug it in it isn't getting seen at all not even a glimpse. I have no experience with your board but what does Windows device manager think of your board? It might help others to help you if you can provider that information. Which version of the IDE? ---

Hello, The device manager manager doesn't even recognize it, its as if i didn't connect anything. for the IDE i am using the version 2.3.4. ---

You are using a usb micro cable? ---

Make sure your cable is a data/sync cable and not a charge-only cable; the latter often are supplied with power banks and bluetooth speakers. ---

Hello, Well i am pretty sure it can send data as i have tested it with microbit before, and my phone. But, in caase do you know if arduino manufactures the cables necessary ? Because when i did some research i learned it takes USB 2.0 i am note sure if that is correct ---

Hi @shloky1. Please try this experiment and then report back with the results: 1. Connect your Arduino board to your computer with the USB cable. 2. Press and release the reset button on your Arduino board quickly twice. 3. If it is already open, close the **Tools \> Port** menu in Arduino IDE. 4. Open the **Tools \> Port** menu in Arduino IDE. Now please [reply](https://meta.discourse.org/t/discourse-new-user-guide/96331#replying-11) here on the forum topic with the answers to the following questions: - Do you now see the LED on the board pulsing? - Do you see a port for the board in the **Tools \> Port** menu? > [@shloky1](#): > > i am pretty sure it can send data as i have tested it with microbit before, and my phone. It should be fine then. Having a defective, damaged, or charge-only cable is a common cause of the "isn't getting recognized" problem, but only one of the potential causes. > [@shloky1](#): > > do you know if arduino manufactures the cables necessary ? Arduino does not manufacture USB cables, but Arduino does sell a nice one on the Arduino Store: > **[Arduino USB Type-C® Cable 2-in1](https://store.arduino.cc/en-ie/products/usb-cable2in1-type-c)** > > Now you can connect your Arduino boards with the official Arduino USB Cable.

The arduino is pulsing the little LED "L" is pulsing slowly and dimming each time. But even when i connected it i still don't see it on the ports. It still just shows the usual Com 9 ;7 ; 3 ; 10; 11. BTW i tried connecting to each one and uploading the code and none of them worked. ---
